'King of Israel' in the Bible

The words of Amos, who was among the sheepherders of Tekoa, which he saw [in a divine revelation] concerning Israel in the days of Uzziah king of Judah, and in the days of Jeroboam the son of Joash, king of Israel, two years before the earthquake.

Then Amaziah, the priest of Bethel [site of the golden calf shrine], sent word to Jeroboam king of Israel, saying, “Amos has conspired against you in the midst of the house of Israel; the land is unable to endure all his words.
